REFRIGERATOR.

SPECIFICATION formingpart of Letters Patent No. 233,772, dated October 26, 1880.

Application filed May 3, 1880.

To all whom it may concern:

Be it known that I, WALTER Knncn, of the city of New York, in the county and State of New York, have invented certain new and useful Improvements in Refrigerators, of which the following is a specification.

My invention consists in the combination, in a refrigerator, of a foodchamber, an icebunker, and a series of tubes extendin g there- 10 from having open lower ends, affording communication with said food-chamber, and each composed of telescopic sections to permit of their extension or contraction. I also, preferably, combine with the above a removable 1 drip-pan or trough, into which the open lower ends of the tubes extend, whereby I afford provision for conveniently contracting the tubes to permit the removal of the pan or trough,

In the accompanying drawings, Figure 1 represents a vertical section of a refrigerator embodying my invention; and Fig. 2 represents a vertical section thereof at right angles to Fig. 1 upon the dotted line m, Fig. 1.

2 Similar letters of reference designate corresponding parts in all the figures.

A designates the inner sheet-metal casing of a refrigerator, which may be inclosed in a wooden casing with suitable non-conducting 3o material. 7

A designates the food-chamber of the refrigerator, which is furnished with a door, B; and A designates the ice -chamber thereof, separated from the food-chamber by a parti- 55 tion, 0, and into which ice may be introduced through a door in the end or top thereof.

In the partition 0, at or near the upper edge thereof, are holes or openings for the passage of air from the food-spaceAinto the ice-cham- 0 her A and these holes may consist of notches a in the upper edge of said partition, or of holes 1) near the upper edge, either one or both forms of openings being used, as may be desired.

Arranged at the lower side of the ice-chainber A is an ice-bunker,D, which is removable, so as to permit of its being readily cleaned. It may be withdrawn when desired through the door in the ice-chamber, through which the ice is introduced. This removable ice-bunker (No model.)

of dirt contained in the ice and released by the melting thereof to be readily washed out. With a stationary ice-bunker the removal of dirt and sediment is a much more tedious oporation.

E designates tubes, of which any number (more or less) may be employed, and which are suspended from the ice-bunkerD. These tubes constitute flues or airducts, through which the warm air entering theicechamberA from the food-space A through the openings a 1) falls as it becomes cooled by contact with the ice, and as the warm air is drawn in through said holes by the falling of the cooled air a continu- 6 ous circulation is kept up, upon which continuous circulation largely depends the efficiency of a refrigerator.

The tubes E may be furnished with perforations 8 in the side, as illustrated in Fig.2, for the purpose of producing more effective circulation.

F designates a trough, which collects the water formed by the melting ice, which descends through the tubes E, and into which the 7 5 lower ends of said tubes project.

In order to provide for withdrawing the trough to empty it without disturbing theicebunker, I have represented each of the tubes E as composed of two telescopic sections, a d, the lower section, d, being fitted over the upper one, 0, and adapted to be adjusted upward on the said section 0, asin certain of the tubes shown in Fig. 2, and held in such elevated position by friction while the trough F is removed and replaced.

As shown clearly in Fig. 2, the tubes E are furnished at their lower ends with projecting prongs or feet 6, upon which they rest, to permit them to discharge the water descending 0 through them 5 but their lower edges might be notched to effect the same result.

The lower ends of the tubes being open, an1- ple provision is afforded for the circulation of air down thetubes and into the food-chamber, 5 uninterrupted communication being afforded between the two. 1

By my invention I produce a refrigeration in which the circulation of the air from the foodspace through the icechamber is con- 10c tinnous and rapid, and certain parts of which may be readily removed for cleaning.

I am aware that refrigerators have been constructed in which were combined a food-space, an ice bunker or chamber in communication with said food-space, and a series of tubes extending downward from said ice-bunker, and providing for the downward circulation of cooled air; and I do not, therefore, claim this as my invention.

What 1 claim as my invention, and desire to secure by Letters Patent, is

1. The combination, in a refrigerator, of a food-chamber, an ice-bunker, and a series of tubes extending therefrom having open lower ends, affording communication with a food- WALTER KEEGH. Witnesses o E. P. JEssUP, CHANDLER HALL.
